OF SAME PLACE.

SPOOL-RACK FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 460,475, datedSeptember 29, 1891. Application filed June 25, 1891- Serial No. 397,495.(No model.)

To all whom it may concern.-

Be it known that I, EDUARD KOLBER, of the city, county, and State of NewYork,have invented anew and Improved Spool-Rack, of which the followingis a full, clear, and exact description.

The object of the invention is to provide a new and improved spool-rackdesigned for use on sewing-machines, tables, and other devices, servingto holda number of spools and guiding the thread of any of the spools tothe proper mechanism of the device on which the rack is employed, thelatter being simple and durable in construction and securely locking theseveral spools in place.

The invention consists of certain parts and details and combinations ofthe same, as will be hereinafter described, and then pointed out in theclaims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of the improve ment as applied on the armof a sewing-machine. Fig.2 is an enlarged plan view of the improvement.Fig. 3 is a transverse section of the same on the line 3 3 of Fig. 2.Fig. 4 is an inverted plan View of the same. Fig. 5 is a plan View of amodified form of the improvement, and Fig. 6 is a transverse section ofthe same.

As illustrated in Fig. 1, the device is applied to the arm of asewing-machine and is provided with two rows of spools, the thread ofany one of which is passed to the usual sewing-machine mechanism to befed to the needle. The spool-rack is provided with asuitably-constructed frame A, fastened in any suitable manner to the armof the sewing machine, table, or other device on which the rack is to beapplied.

The frame A is provided with a horizontally-extending top, in the middleof which is arranged alongitudinallywextending partition B, supporting aseries of transverselyextending spindles C, on which are held to rotateloosely the spools D, carrying the thread. As shown in Fig. 2, eachspindle extends a suitable distance from each side of the partition B,each projecting end of the bearings A, arranged on the under side ofspindle carryingaspool. The thread is taken from the spool to be usedand passed forward through an eye E, arranged on a thread guide E,fastened to the front end of the partition B. The eyes E extend midwaybetween the transverse partition 13 and the sides F of the frame, asplainly shown in Fig. 2.

The sides F are made movable and fitted to slide transversely, theinside of each side being formed with a small recess engaging theoutermost end of the respective spindle C, so that each of the latterhas a bearing at its free end when the sides F are in their innermostpositions. Each of the sides F is formed with a number oftransversely-extending rods G, passing along the under side of the topof the frame A, the said rods extending through the top of the frame A.

The free end of each of the rods G is provided with a collar G, whichlimits the lateral outward sliding motion of the respective side F, thesaid collar abutting against the bearing A when the side F is moved toan outermost position. The rods G for each side F are of such a lengththat when the said sides are moved into an outermost position thedistance between the inner surfaces of the sides and the free ends ofthe spindles O is sufficient to permit removal or insertion of one-ofthe spools D on the respective spindle.

A locking-bar H is employed to lock the sides F to the frame when thesaid sides are in an innermost position, as illustrated in Figs.

2, 3, and 4. This locking-barH passes through corresponding apertures inthe sides F and.

through the bearings A formed on the under side of the top of the frameA.

One end of the locking-bar H is provided, with a head H abutting againstthe outside of one of the sides F, while the other end of the said barprojects beyond the other side F and is adapted to be engaged by a lookI of 5 any approved construction, so that when the lock is applied thebarH is held in place, thus locking the sides F in position on the frameA. When the device is in this position, the spools D, held on thespindles O, cannot be 100 removed, but the said spools are free torevolve on the said spindles to unwind the thread as the latter is takenup by the machine. As illustrated in Figs. 5 and 6, the transversespindles C are dispensed with, the partition B being instead providedwith recesses B each adapted to be engaged by one of the flanges D ofthe spool D. The other flange of the spool engages a similarly-shapedcircular recess F, formed in the respective side F, so that the spool isfree to revolve in the said recess B and F when the side F is locked tothe frame A by the bar H in the manner above described. To preventfriction of the spool D in the recesses B and F, each side F is providedwith a short pin or spindle F engaging the central aperture of thespool, as plainly shown in the said Figs. 5 and 6, the said pinprojecting centrally from the recess F.

It is understood that any desired number of spindles may be arranged onthe partition B provided that the latter is made long enough toaccommodate a large number of spools. If desired, the device may beconstructed with but one row of spools. In this case the partition Bforms a fixed side for the frame A, while one of the sides F is mademovable in the manner described.

It is understood that in this construction the spindles C only projectfrom one side of the partition B and the top of the frame only reachesfrom one side to the said partition.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. A spool-holder comprising the frame havingthe horizontal base or top A, provided with outwardly-movable walls orsides F F, an intermediate parallel wall or partition provided withtransverselyprojecting spoolspindles, and a locking device to retain themovable walls or sides in position, substantially as shown anddescribed.

2. A spool-rack comprising a frame provided with a top and a longitudinally-extending partition, spindles held on the said partition andextending transversely, sides parallel with the partition and fitted toslide laterally on the said frame toward and from the said partition tolock the spools held on the spindles in placebetween the sides andpartition, and a lockingbar passing transversely through the said sidesand hearings in the said frame to fasten the said sides to the saidframe, substantially as shown and described.

3. A spool-rack comprising a frame provided with a top and alongitudinally-extending partition, spindles held on the said partitionand extending transversely, sides parallel with the partition and fittedto slide laterally on the said frame toward and from the said partitionto lock the spools held on the spindles in place between the sides andpartitions, and rods extending transversely from the said sides andfitted to slide in bearings on the said frame, the free end of the rodsbeing provided with stop-collars to limit the outward movement of thesides, substantially as shown and described.

at. A spool-rack comprising a frame provided with a top and alongitudinallyextending partition, spindles held on the said partitionsand extending transversely, sides parallel with the partition and fittedto slide laterally on the said frame toward and from the said partitionto lock the spools held on the spindles in place between the sides andpartition, a locking-bar passing transversely through the said sides,bearings in the said frame to fasten the said sides to the said frame,and eyes supported at one end of the said frame to guide the threadsunwound from one of the spools, substantially as shown and described.
